find the value of x of given figure and solve this question step by step plzz help question number D

Alinara [238K]

Answer:

x=15 cm

Step-by-step explanation:

The two triangles in the diagram are:

ABC and BDC

First we have to find the third side (hypotenuse) of BDC so that we can use it to find the value of x.

Hypotenuse is the largest side of a triangle which is usually in front of the right angle.

So in BDC

$Base = BD =10cm\\Hypotenuse = BC = ?\\Perpendicular = CD = 2\sqrt{11}cm$

Applying Pythagoras theorem:

$(Hypotenuse)^2 = (Base)^2 + (Perpendicular)^2\\BC^2 = BD^2 + CD^2\\BC^2 = (10)^2 + (2\sqrt{11})^2\\BC^2 = 100+(2^2 * 11)\\BC^2 = 100+(4*11)\\BC^2 = 100+44\\BC^2 = 144\\\sqrt{BC^2} = \sqrt{144}\\BC = 12cm$

Solving for triangle ABC

$Base = BC = 12 cm\\Perpendicular = AB = 9 cm\\Hypotenuse = AC = x\\$

Applying Pythagoras theorem

$AC^2 = BC^2+AB^2\\x^2 = (12)^2 + (9)^2\\x^2 = 144+81\\x^2 = 225\\\sqrt{x^2} = \sqrt{225}\\x = 15cm$

Hence,

x=15 cm

What is the solution of log2x + 6 8 = 3? (6 points)

photoshop1234 [79]

Step-by-step explanation:

$log(2x) + 68 = 3 \\ log(2) + log(x) + 68 = 3 \\ log(x) = - 65.30103 \\ x = {10}^{ - 65.30103} = \\ x = 5 \times {10}^{ - 66}$

Answer:

<h3><em>isosceles</em></h3>

An isosceles triangle is a triangle that has two sides of equal length.

An acute triangle is a triangle with three acute angles (less than 90°).

A scalene triangle has all its sides of different lengths. Equivalently, it has all angles of different measure.

An equilateral triangle is a triangle in which all three sides are equal.
